MILITARY SHOULDER-ARM.

Specification of Letters Patent.

Patented Jan. 25, 1916.

Application filed November 5, 1915. Serial No. 59,801.

To all whom it may concern:

Be it known that I, THOMAS C. J OHNsoN, a citizen of the United States,residing at New Haven, in the county of New Haven and State ofConnecticut, have invented a new and useful Improvement in MilitaryShoulder-Arms; and I do hereby declare the following, when taken inconnection with the accompanying drawings and the characters ofreference marked thereon. to be a full. clear, and exact description ofthe same, and which said drawings constitute part of this application,and represent, in

Figure l a view in right hand side elevation of the middle portion of amilitary shoulder-arm constructed in accordance with my invention. Fig.2 a reverse plan view thereof. Fig. 3 a view thereof partly in righthand side elevation and partly in rertical longitudinal section. Fig. 4a detached broken side view of the forward end of the tang of thebox-magazine of the gun. Fin; 5 a detached view in rear elevation of theforeetoc c. Fin. 6 a detached View in front elevation of the butt-stock.

My invention relates to an improvement in military shoulder-arms. theobject being" to provide simple and reliable means for holding theforestoclr against longitudinal forward d splacementwithout imposing anystrain upon the barrel of the arm.

With these ends in View. my invention con ists in a militaryshoulder-arm having; certain details of construction as will behereinafter described and pointed out in the claims.

In carrying out my invention as herein shown, the forestock 2 is formednear its rear end with a vertical locking-recess 3 entering it from itslower face for the reception of a lockin, z-lu 4 upstanding from alocking-arm 5 forming an integral, horizontal extension of the forwardtang 6 of the box'magrazine 7, the lower face of the fore'stock beingformed with a longitudinal clearance recess or groove 8 for thereception of the said locking-arm 5 and the said recess 8 intersectingat its forward end the locking-recess 3. When the lug 4: is crowded intothe recess 3. the forestock 2 is securely held against longitudinalforward displacement without the imposition of any strain upon thegun-barrel 9. As shown, and by preference, the rear face of the lug i isslightly tapered as 'atlO to co-act with the correspondingly taperedrear wall of the recess 3 so as to insure the drawing of the forestocksolidly into place in assembling the gun. Also, as shown, the forwardwall of the recess 3 and the forward face of the lug 4 are rounded,though this is not necessary.

As shown. the forestock 2 is formed at its rear end with a tenon l2entering a shallow recess 13 in the forward face of the lower portion ofa receiverextension 14 screwed upon the forward end of the receiver 15which is provided wi h a threaded opening 16 for the reception of thethreaded shank 17 of the gun-barrel 9. The butt-stock 18 which may he ofany approved construction, is formed at its forward end. as shown, wi ha tenon 19 entering a shallow recess 20 in the rear face of the receier-extension 14. A screw 21 passing upward through the tang 6 into athreaded boss 22 upon the rear face of the. receiver-extension 14secures the said tang" in place. As shown the tanq' 6 is formed upon i supper face with a circular locking boss 23 entering a correspondingrecess 24: in the lower face of the receivenextens on 14. wherehv thetang is i self held again t endwise dis lacement and the screw 21 relieed of strain. So far as my pre ent invention is conce ned thereceivenextension might be made integral with the receiver.

The term receiver in the claims is to be understood as covering thereceiver whether its extension is integral or otherwise except in thoseclaims in which the receiver-extension is specifically mentioned.

I claim 1. In a military shoulder-arm. the combination with the receiverthereof. of a forestock formed in its lower face with a lockinn-recess.and a tang connected to the receiver and provided with a forwardextension entering the said recess for holding the said 'forestockagainst longitudinal forward displacement.

2. In a military shoulder-arm. the combination with the receiverthereof. of a receiver-extension, a forestock provided in its lower facewith a locking-recess, and a tang secured to the said receiver-extensionand formed with an integral locking-arm provided at its forward end withan upstanding locking-lug entering" the recess in the forestock forholding the same against forward longitudinal displacement.

3. In a military shoulder-arm, the combination with the receiverthereof, of a receiver-extension, a forestock provided in its lower facewith a locking-recess, and atang secured to the said receiver-extension,provided with a forwardly extending lockingarm entering the said recessin the fore stock, and also provided with a locking-boss entering thesaid receiver-extension.

4. In a military shoulder-arm, the combr nation with the receiverthereof, of a forestock formed in its lower face with. a locking-recess,and a box-magazine provided with a forwardly extending tang, having anintegral locking-arm entering the said recess for holding the saidforestock against longitudinal forward displacement.
